Best way to validate, insert, and redirect?

[rapmonkey]

What is the best way to validate form data, interact with a MySQL database (insert or update), and then redirect the user to a specific page? Thanks for any help! 😃

RegEx for validation

Normal mySQL integration via PHP for inserting

Either a switch, or if()else() statements for redirection with a header() redirect, or link.
